Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a switch device using a switch body in which a transparent conductive portion is brought into contact with and separated from a transparent electrode provided on a transparent substrate.

[Prior Art] For example, in a power window switch device for an automobile, where the entire surface is illuminated at night, a switch body is formed by polymerizing a conductive transparent film on a transparent glass plate with a transparent electrode on its surface.
A knob is arranged on the front side of this switch body, and a light emitting diode is arranged on the back side, and when the knob is operated, a part of the transparent film is pressed by the pressing protrusion formed on the knob, making it transparent. There is a structure in which the switch is turned on by contacting the electrode, and at night the light emitting diode is energized to emit light and the light is transmitted through the switch body and emitted upward. I have to. However, with this configuration, when the knob is operated, the pressing protrusion of the knob only presses the transparent film, so there is a problem in use that the operating feeling is not so good.

In order to solve this problem, it may be possible to provide a moderation mechanism between the knob and the switch body to give a sense of operation due to the sense of moderation, but this would prevent the light passing through the switch body at night. There is a contradictory problem in that the moderation mechanism prevents the illumination of the entire surface, making it difficult to illuminate the entire surface.

[Purpose of the invention] The present invention has been made in view of the above-mentioned circumstances, and its purpose is to provide a switch device that is capable of illuminating the entire surface and that also provides a reliable sense of operation through moderation.

[Summary of the invention] The present invention is a switch body that brings a transparent conductive part into contact with and separates from a transparent electrode provided on a transparent substrate. The switch body is characterized by a configuration in which a moderation body is disposed and a light source is disposed on the other surface side, and the light transmitted through the switch body is also transmitted through the moderation body.

The knob 14 is held in a horizontal state by contacting the operating portions 9b and 10b of the knob 10 from above.

The switch case 1 is fitted into a storage opening 19 formed in a rest arm 18 on the inner surface of a door of an automobile.

Next, the operation of this embodiment will be explained.

When the knob 14 is in its original horizontal position as shown in FIG. The pressing protrusion 16a is the moderation part 9
As shown in FIG. 2, press the action part 9b of
The upper part of the flexible part 9a is elastically bent and deformed downward, and the lower end part of the acting part 9b presses a part of the transparent film 6 to come into contact with the transparent electrodes 4a, 4b. , the transparent electrodes 4a and 4b are short-circuited by a part of the transparent film 6, resulting in a one-side switch-on (down-switch-on) state. As a result, a window drive motor (not shown) is rotationally driven in a fixed direction to lower the door window glass. Then, when the pressing force on the left side of the knob 14 is released, the flexible portion 9 of the moderation portion 9
a returns to the protruding state, the knob 14 returns to the horizontal state, and the short circuit between the transparent electrodes 14a and 14b due to a part of the transparent film 6 is released (down switch-off). Conversely, when the knob 14 is in the horizontal original position, the knob 14
When the other side, the right side, is pressed and rotated to the right, the pressing protrusion 1 of the indicating section 17

The lower end of the transparent film 6 presses a part of the transparent film 6 to come into contact with the transparent electrodes 4c, 4d, so that the part of the transparent film 6 between the transparent electrodes 4c, 4d short-circuits the other side switch ( state. As a result, the window drive motor is rotated in the opposite direction to raise the door window glass.

On the other hand, at night, the light emitting diodes 7, 7
is energized and the light emitting surfaces 7a, 7a begin to emit light. The light passes through the switch body 3 and the moderation body 8 and is emitted upward, making it possible to illuminate the entire area. This allows knob 1
1 is in its original position in the horizontal state shown in FIG. will be released.
For example, when the knob 11 is rotated to the left as shown in FIG.
By moving away from the indicator, the degree of light emission of the indicator 17 becomes slightly smaller than that of the indicator 16. Also, when the knob 11 is rotated to the right, the indicator on the left side is moved by the same principle. The degree of light emission of the section 16 is smaller than that of the indicator section 17 on the right side.

As described above, according to this embodiment, the light from the light emitting diodes 7, 7 passes through the switch body 3 and the moderation body 8 and is emitted upward, so that the entire surface can be illuminated. Indication part 1 of knob 14
